All pregnancies have a small chance of having a baby with a genetic abnormality. Often this is the result of an error in the number of chromosomes - too many or too few. Majority of fetal chromosome abnormalities result in miscarriage.
However, there are a small, but significant proportion of chromosome abnormalities that persist to term, and if undetected, can manifest as chromosome disease syndromes after birth. These chromosomale abnormalities include Down Syndrome (Trisomy 21), Edward Syndrome (Trisomy 18), Patau Syndrome (Trisomy 13) as well as a range of sex chromosome abnormalities (SCAs) such as Turner Syndrome (45, XO), Klinfelter Syndrome (47, XXY), Triple X Syndrome(47, XXX) and Jacob Syndrome (47, XYY).
In addition to these 7 chromosome diseases, the fetus may also lose a small part of a chromosome and result in a microdeletion syndrome. Although rare, the 7 most frequent microdeletion syndromes include 22q 11.2 (DiGeorge), 1 q36, 2q33.1, 5p (Cri-Du-Chat), 8q23-24 (Langer-Giedion), and 15q 11 – 13 (Angleman/ Pradar-Willi). The Daisy Prenatal Test – a revolutionary advanced non-invasive prenatal screening tests will help to get to know the chromosomal health of your baby as early as 10 weeks into pregnancy.
